i386: Wrong code with __builtin_parityl [PR112672]

gen_parityhi2_cmp instruction clobbers its input operand, so use
a temporary register in the call to gen_parityhi2_cmp.

PR target/112672

gcc/ChangeLog:

* config/i386/i386.md (parityhi2):
Use temporary register in the call to gen_parityhi2_cmp.

gcc/testsuite/ChangeLog:

* gcc.target/i386/pr112672.c: New test.

(cherry picked from commit b2d17bdd45b582b93e89c00b04763a45f97d7a34)
